Logical safety system for triggering off the protection action of a safety actuator

Creators

Description

This invention applies in particular to the emergency triggering of safety actuators controlling the shutdown of a nuclear reactor. This logical safety system includes four redundant lines each composed, inter alia, of a logical circuit for controlling the triggering of a protection action, a logical alarm circuit connected to the control circuit and a logical inhibiting circuit making it impossible to inhibit several alarm circuits simultaneously

Abstract (French)

Cette invention s'applique notamment aux declenchements urgents d'actionneurs de surete commandant l'arret d'un reacteur nucleaire. Ce systeme logique de securite comprend quatre voies redondantes constituees chacune notamment par un circuit logique de commande de declenchement d'action de protection, un circuit logique d'alarme relie au circuit de commande, et un circuit logique d'inhibition grace auquel il est impossible d'inhiber simultanement plusieurs circuits d'alarme
